DETAILED DESCRIPTION

This disclosure details an exemplary quarter panel bracket system for pillar assembly adjustment. The bracket system provides for adjustment of a vehicle panel relative to a pillar to achieve a desired fit and finish relative to other panels and final installed vehicle components.

FIG. 1 shows a vehicle 10 that includes a plurality of vehicle panels that are secured together to provide a vehicle body. In one example, the plurality of vehicle panels includes a quarter panel 12 that is attached to one side 14 of the vehicle 10 behind a vehicle door 16. The quarter panel 12 includes a main portion 12 a that extends along the vehicle side 14 and over a wheel well 18. The quarter panel 12 also includes a pillar attachment portion 12 b that extends from a rear end of the main portion 12 a and wraps around a rear side 20 of the vehicle 10 to be attached to a pillar 22, such as a D-pillar for example.

In one example, the quarter panel 12 is fixture-set in a body shop. A position of the quarter panel 12 impacts fit and finish to a rear closure vehicle panel 24 and a side closure vehicle panel 26 at the vehicle door 16. Additionally, the position of the quarter panel 12 impacts fit and finish to other final installed exterior vehicle components such as a tail-light 28 and a pillar panel 30, for example, as shown in FIG. 2. The disclosure provides a bracket system 40 that is used to achieve the desired fit and finish. In order to achieve the desired fit and finish the bracket system 40 should be able to provide for adjustment of the quarter panel 12 in a fore/aft direction relative to the pillar 22 along an X-axis (FIG. 3B) and in a vertical direction along a Z-axis (FIG. 4).

In one example shown in FIGS. 3A-3B, the bracket system 40 includes a first portion 42 fixed to the quarter panel 12 and a second portion 44 that is moveable relative to the first portion 42 for adjustment purposes. At least one first fastener 46 holds the first 42 and second 44 portions together prior to assembly of the quarter panel 12 to the pillar 22. In one example, the first portion 42 comprises a first bracket having a first end 48 fixed to the quarter panel 12 and a second end 50 with a first opening 52 (FIG. 8), and the second portion 44 comprises a second bracket having a first end 54 to be fixed to the pillar 22 and a second end 56 with a second opening 58 (FIG. 8). The first 52 and second 58 openings are positioned in an overlapping relationship with each other.

The at least one first fastener 46 is inserted through the first 52 and second 58 openings to hold the first 42 and second 44 brackets together. The first end 48 of the first bracket 42 is held fixed to the quarter panel 12 by a fixed attachment interface 60 shown schematically in FIG. 3A. The fixed attachment interface 60 can comprises a fastener interface, a welded interface, or any other type of suitable fixed attachment structure.

In one example, the quarter panel 12 is shipped to a body shop with the bracket system 40 fixed to the quarter panel 12 and with the first 42 and second 44 brackets fixed together with the fastener 46. The quarter panel 12 is then loaded into an assembly fixture (not shown) that is used to position the quarter panel 12 relative to the pillar 22. Once the quarter panel 12 is loaded, the fastener 46 is loosened to adjust a position of the second bracket 44 relative to the first bracket 42 and to the pillar 22 to achieve a desired position of the quarter panel 12 relative to the pillar 22.

Once in the desired position, at least one second fastener 62 secures the second bracket 44 to the pillar 22 subsequent to the adjustment. The first fastener 46 is then re-tightened after the adjustment to hold the quarter panel 12 fixed in the desired position relative to the pillar 22.

As such, the subject disclosure provides a compensation bracket system 40 that allows fore/aft and vertical adjustment of the quarter panel 12 at the upper D-pillar attachment area. This bracket system 40 provides for a part and cost reduction as a separate compensator element is not required to be installed on the pillar. Further, this bracket system 40 retains the factory-set position of the upper D-pillar attachment for an end user if the panel is subsequently removed.

In one example, one of the first 52 and second 58 openings has a different size and/or shape than the other of the first 52 and second 58 openings to allow for adjustment. In one example shown in FIG. 8, the first opening 52 in the first bracket 42 comprises an elongated opening or slot that allows for adjustment in both the fore/aft direction along the X-axis and the vertical direction along the Z-axis. The second opening 58 comprises a smaller opening that is formed in the second end 56 of the second bracket 44 and is positioned to overlap with the elongated opening 52 in the first bracket 42. In one example, the second opening 58 can comprise a circular opening or can also comprise an elongated opening or slot. The first fastener 46 is inserted through the aligned openings 52, 58 to secure the brackets 42, 44 together.

The first end 54 of the second bracket 44 includes an additional opening 64 through which the second fastener 62 is inserted. A corresponding pillar opening 66 is formed within the pillar 22 and the bracket opening 64 is aligned with the pillar opening 66. In one example, the additional opening 64 comprises an enlarged opening relative to the size of the pillar opening 66 to allow for adjustment in the vertical direction. In one example, the enlarged opening 64 has a square shape; however, the opening can have other shapes as well.

In one example, an anti-rotation feature 70 couples the first 42 and second 55 brackets together. The anti-rotation feature 70 is separate from the aligned openings 52, 58 of the brackets 42, 44. In one example, the anti-rotation feature 70 comprises at least one finger or tab 72 that extends outwardly of one of the first 42 and second 44 portions and at least one elongated opening 74 formed within the other of the first 42 and second 44 portions that receives the tab 72. In one example, the tab 72 is formed to extend away from the second end 50 of the first bracket 42 and in a direction that is transverse to a plate body of the first bracket 42. In one example, the elongated opening 74 is formed in a plate body of the second bracket 44 and is separate and spaced apart from the second opening 58. The tab 72 is received within the opening 74 and is moveable within the opening 74 when the first fastener 46 is loosened. The elongated opening 52 in the first bracket 42, along with the anti-rotation tab 72, allows the second bracket 44 to adjust in the fore/aft direction when the first fastener 46 is loosened without the bracket 44 falling out of position.

In one example, the first fastener 46 comprises a clamping bolt having an enlarged head portion 80 and a narrower threaded body portion 82. A washer 84 is installed between the enlarged head portion 80 and a surface of the first bracket 42 that surrounds the first opening 52. A threaded nut 86 is fixed to a rear surface of the second bracket 44, and the threaded body portion 82 is threaded into the nut 86 as the first fastener 46 is tightened. When the first fastener 46 is loosened for adjustment purposes, the nut 86 retains the fastener 46 to the bracket system 40 such that the fastener 46 does not fall off.

In one example, the second fastener 62 comprises a clamping bolt having an enlarged head portion 88 and a narrower threaded body portion 90. A washer 92 is installed between the enlarged head portion 88 and a surface of the second bracket 44 that surrounds the opening 64. A threaded nut 94 is fixed to the pillar 22, and the threaded body portion 90 is threaded into the nut 94 as the second fastener 62 is tightened to fix the second bracket 44 to the pillar 22.

In one example, the first bracket 42 comprises a rigid metal plate that provides for flat bracket body surfaces at the first 48 and second 50 ends. In one example, the second bracket 44 comprises a rigid metal plate that provides for flat bracket body surfaces at the first 54 and second 56 ends.

In the example shown in FIGS. 3A-3B, 4, 5A-5B, and 8, the flat plate body portions of the first 54 and second 56 ends of the second bracket 44 are perpendicular to each other (FIG. 3B). In the example shown in FIGS. 6A-6B, 7, and 9A-9B, the flat plate body portion of the first end 54 of the second bracket 44 is at an oblique angle relative to the flat plate body portion of the second end 56 of the second bracket 44 (FIG. 6B). In one example, the flat plate body portion of the first end 54 of the second bracket 44 is orientated at a forty-five degree angle relative to the flat plate body portion of the second end 56. This angled configuration provides for improved tooling access to the attachment interface. This angled configuration includes the same anti-rotation feature and aligned openings as shown in the configuration of FIG. 8.
